5 Main Causes of Knee Pain You Should Know

Added: 2026-05-17

Knee pain can result from five primary causes: (1) Osteoarthritis, where cartilage between knee bones gradually wears down with age; (2) Excess body weight, which increases pressure on knee joints; (3) Vitamin D and calcium deficiency, which weakens bones and muscles supporting the knee; (4) Trauma such as falls, sports injuries, or torn knee ligaments; and (5) Inflammatory conditions including high uric acid levels and rheumatoid arthritis. Early awareness and addressing these causes can help prevent complications like reduced mobility, chronic inflammation, and joint damage.
